S_DebandRemoves banding artifacts from a clip by diffusing pixels across the banded areas, while keeping the original edges intact. To use this effect, first select Show:Edges and adjust the edge threshold until the banding edges just disappear, leaving only the desired real edges. Then select Show:Result to see the result. If you still see some banding, increase Diffuse Threshold and/or Diffuse Radius.In the Sapphire Blur+Sharpen category.

Parameters:
-
Load Preset:
Push-button
.
Brings up the Preset Browser to browse all available presets for this effect.
-
Save Preset:
Push-button
.
Brings up the Preset Save dialog to save a preset for this effect.
-
Mocha:
Default:
0,
Range:
0 or greater.
Brings up the Mocha window for tracking footage and generating masks.
-
Blur Mocha:
Default:
0,
Range:
0 or greater.
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.
-
Mocha Opacity:
Default:
1,
Range:
0 to 1.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.
-
Invert Mocha:
Check-box, ย Default:
off.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.
-
Resize Mocha:
Default:
1,
Range:
0 to 2.
Scales the Mocha Mask. 1.0 is the original size.
-
Resize Rel X:
Default:
1,
Range:
0 to 2.
The relative horizontal size of the Mocha Mask.
-
Resize Rel Y:
Default:
1,
Range:
0 to 2.
The relative vertical size of the Mocha Mask.
-
Shift Mocha:
X & Y, ย Default:
screen center.
Offsets the position of the Mocha Mask.
-
Dilate Mocha:
Default:
0,
Range:
-100 to 100.
Dilates or erodes the Mocha Mask by this pixel amount before using.
-
Dilation Quality:
Popup menu, ย Default: Fast
.
Selects whether Dilate Mocha adusts quickly in default Fast mode or looks better in High quality mode.
-
Fast:
Dilate Mocha in Fast mode for quick adjustments.
- High: Dilate Mocha in High quality mode for a better looking mask shape.
- High: Dilate Mocha in High quality mode for a better looking mask shape.
-
Fast:
Dilate Mocha in Fast mode for quick adjustments.
-
Bypass Mocha:
Check-box, ย Default:
off.
Ignore the Mocha Mask and apply the effect to the entire source clip.
-
Show Mocha Only:
Check-box, ย Default:
off.
Bypass the effect and show the Mocha Mask itself.
-
Combine Masks:
Popup menu, ย Default: Union
.
Determines how to combine the Mocha Mask and Input Mask when both are supplied to the effect.
-
Union:
Uses the area covered by both masks together.
- Intersect: Uses the area that overlaps between the two masks.
- Mocha Only: Ignore the Input Mask and only use the Mocha Mask.
- Intersect: Uses the area that overlaps between the two masks.
-
Union:
Uses the area covered by both masks together.
-
Edge Threshold:
Default:
2,
Range:
0 to 255.
The amount by which adjacent pixels must differ to constitute a real desired edge. A value of 1.0 represents the smallest possible difference at 8 bits. This parameter should be set high enough that none of the bands appear as edges, but low enough that all the real edges are still detected.
-
Grow Edges:
Default:
0,
Range:
0 or greater.
Amount to grow the detected edges in approximate pixels. Increasing this parameter can prevent diffusion in areas that are near edges, but not on an edge.
-
Diffuse Threshold:
Default:
1,
Range:
0 or greater.
The maximum color difference allowed when diffusing pixels. This parameter is automatically scaled by the edge threshold. Increasing it can give better results when there is a gradient within the bands. Decreasing it will reduce diffusion in areas where there are no edges.
-
Diffuse Radius:
Default:
12,
Range:
0 or greater.
The maximum radius of pixel diffusion, in approximate pixels. A larger value will remove banding more effectively in large areas with uniform colors, while a smaller value will give a better result in areas with many small color regions.
-
Pre Blur:
Default:
0,
Range:
0 or greater.
Blurs the source before diffusing pixels.
-
Post Blur:
Default:
0.5,
Range:
0 or greater.
Blurs the result after diffusing pixels. Use this parameter to reduce noisiness in the result.
-
Show:
Popup menu, ย Default: Result
.
Selects the type of output.
-
Result:
Shows the final result.
- Edges: Shows the edges of the image, where adjacent pixels differ by more than Edge Threshold. Use this mode to help fine-tune the edge detection parameters.
- Edges: Shows the edges of the image, where adjacent pixels differ by more than Edge Threshold. Use this mode to help fine-tune the edge detection parameters.
-
Result:
Shows the final result.
-
Mask Use:
Popup menu, ย Default: Luma
.
Determines how the Mask input channels are used to make a monochrome mask.
-
Luma:
the luminance of the RGB channels is used.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
- Alpha: only the Alpha channel is used, or if there is no valid Alpha channel the Red channel is used.
-
Luma:
the luminance of the RGB channels is used.
-
Blur Mask:
Default:
0.05,
Range:
0 or greater.
Blurs the Mask input by this amount before using. This can provide a smoother transition between the masked and unmasked areas. It has no effect unless the Mask input is provided.
-
Invert Mask:
Check-box, ย Default:
off.
If on, inverts the mask input so the effect is applied to areas where the Mask is black instead of white. This has no effect unless the Mask input is provided.
